Seven months after offseason knee surgery, Robert Griffin III said he feels he’s ahead of schedule, but isn’t happy his progress is being hindered by Redskins coach Mike Shanahan’s strict plan for his recovery.

Shanahan has a predetermined timeline of how he plans to handle Griffin’s comeback. That involves participating in training camp contact drills for the first time today.

“I can’t BS that answer. So … no. I don’t like it,” Griffin said yesterday. “There’s some part of it that I do understand. I don’t understand all of it. At the end of the day [Shanahan] gave me his word. We talked privately. I know the whole plan. I’m not telling the whole plan. I don’t understand the whole plan at all and I can’t lie about that.”

Griffin didn’t appear in the Redskins’ preseason opener on Thursday, and isn’t expected to play in any other preseason games. But he said he will be ready for the regular-season opener against the Eagles on Sept. 9.

“There’s no doubt I’m playing Week 1. That’s the way I feel about it,” Griffin said.

The injury could have been avoided if Shanahan had removed Griffin from the Redskins’ wild-card loss to the Seahawks last season after the quarterback was noticeably hurt. Griffin’s knee later buckled and he tore his ACL and LCL in his right knee. Griffin said he and Shanahan have “ironed that out.”
